Copernicus decided this with more of an educated guess than anything. For example is when your standing right next to a plane it's huge Right? Well when it's flying it looks really small. He used the same reasoning for stars. Since it looks small it must be farther away.
Copernicus concluded that stars were farther away than planets because he observed that stars did not exhibit the same apparent motion as planets. While planets appeared to move in relation to the background stars as Earth orbited the Sun, the positions of stars remained fixed relative to each other. This led Copernicus to realize that stars must be much farther away than planets.

How did Copernicus explain the retrograde motions of the planets?
Copernicus explained the retrograde motions of the planets by proposing that the Earth and the other planets revolve around the Sun in circular orbits. He suggested that the appearance of retrograde motion was a result of the varying speeds at which the planets orbited the Sun.
How was Copernicus' idea of planet movement different from ptolemy's?
Copernicus proposed a heliocentric model, where planets revolve around the sun, while Ptolemy's geocentric model placed Earth at the center of the universe with planets orbiting around it. Copernicus' model helped to explain retrograde motion more simply than Ptolemy's epicycles.
What are the similarities beween Copernicus' model of the universe and Ptolemy's model of the universe?
Both Copernicus' and Ptolemy's models aimed to explain the motion of celestial bodies in the sky. However, Copernicus placed the Sun at the center of the universe, while Ptolemy's model had Earth at the center. Both models used the concept of epicycles to explain the retrograde motion of planets.
What did Nicolaus Copernicus think your solar system was?
Nicolaus Copernicus proposed that the Sun, not the Earth, was the center of the solar system and that the planets, including Earth, revolved around the Sun in circular orbits. This heliocentric model challenged the prevailing geocentric view of the time.
Why is Copernicus' model much simpler than Ptolemy's?
Copernicus' model is simpler than Ptolemy's because it places the sun at the center of the solar system, with planets orbiting around it in nearly circular paths. This heliocentric model eliminates the need for complex epicycles, which Ptolemy used in his geocentric model to explain the retrograde motion of planets. Copernicus's model also provides a more elegant explanation for the observed movements of celestial bodies.
Why did Copernicus think that stars are farther from earth than the planets are?
He knew that the planets revolved around the sun in an elliptical orbit.
